LibWeb: Add a dedicated function for parsing HTML length values

Browse source 
Presentation attribute lengths (width, height, etc.) can always be
unit-less (e.g "400") so going via the normal CSS parsing path only
works when the document is in quirks mode.

Add a separate parse_html_length() that always allows unit-less values.
